Description

Technical Field

[0001] This utility model relates to the technical field of descaling and cleaning equipment, and in particular to a descaling and cleaning equipment for a steam generator. Background Technology

[0002] A steam generator, also called a steam heat source machine (commonly known as a boiler), is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of "boiler" refers to a water-filled container heated over a fire, while "furnace" refers to the place where fuel is burned. A boiler consists of two main parts: the boiler and the furnace.

[0003] An existing device and method for removing scale from a steam generator (publication number: CN117361693A) has at least the following drawbacks: This device uses sodium ion exchange resin to replace sodium ions in hard water, removing calcium and magnesium ions contained in the hard water, and further obtaining soft water that is not easily precipitated, thereby eliminating scale. However, after removing hardness ions such as calcium and magnesium, the pH stability of the water decreases, and the softened water is more likely to be weakly alkaline, which aggravates the corrosion of metal materials. Although the softened water removes calcium and magnesium ions, it causes sodium ions to be reconcentrated and significantly increased in the steam generator. In the high-temperature and high-pressure steam generator, sodium ions will combine with impurities such as chloride ions to form salts such as sodium chloride, which will also cause corrosion of metal pipes over a long period of time.

[0010] As a further embodiment of this utility model, the top of the electromagnetic heater is provided with a high-temperature heat insulation layer, the high-temperature heat insulation layer is fixedly connected to the outside of the top of the inner liner, and an outer protective shell is fixedly connected to the top of the high-temperature heat insulation layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When scale accumulates inside the inner tank, open the electric control valve on top of the descaling tank to allow tap water to enter. Simultaneously, add an appropriate amount of descaling agent through the feed pipe. Then, start the drive motor, which drives the turbine to rotate. The turbine's rotation agitates the liquid in the descaling tank, ensuring the descaling agent and tap water are fully mixed, preventing sedimentation and ensuring effective descaling. Close the control valve at the bottom of the water supply valve and open the external control valve of the branch pipe. The branch pipe opens, allowing the descaling liquid to flow into the inner tank through the drain pipe. Start the main body of the steam generator to heat the tank, allowing the agent to fully react with the scale and remove the scale inside. The waste liquid is discharged from the inner tank through the drain pipe. This descaling method is simple to operate, suitable for thin to medium-thickness scale, and causes minimal damage to the equipment.

[0014] 2. When thick or stubborn scale appears on the inner wall of the inner tank, after the main body of the steam generator stops operating, start the control valve to allow tap water from the water tank to enter the inner tank through the inlet pipe. At the same time, adjust the vibration frequency and duration of the ultrasonic transducer through the control panel of the main body of the steam generator to allow the ultrasonic waves to penetrate the vibrating plate and the high-temperature insulation layer into the inner tank, gradually breaking down the scale layer on the inner wall. At the same time, descaling agent from the descaling tank can be added to the inner wall. The descaling agent, in conjunction with the ultrasonic waves, can remove thick or stubborn scale from the inner wall of the inner tank. The ultrasonic transducer can handle narrow gaps or curved pipes and other areas that are difficult for machinery to reach, while avoiding scratching and damaging the metal surface.

A water supply tank 5 is provided on the top of the steam generator. The descaling tank 6 is located on one side of the water supply tank 5. The descaling tank 6 includes a turbine 602, a drive motor 603 and a feeding pipe 605. A housing 604 is fixedly connected to the side of the descaling tank 6 away from the water supply tank 5.

One end of the turbine 602 passes through the descaling tank 6 and is fixedly connected to the output end of the drive motor 603. The feeding pipe 605 passes through and is fixedly connected to the top of the descaling tank 6. A pipe cap 606 is threadedly connected to the top of the feeding pipe 605.

A T-shaped pipe 8 is fixedly connected to the top of the water supply pipe 7 by bolts. An electric control valve 801 is fixedly connected to the outside of both ends of the T-shaped pipe 8 near the several water supply pipes 7.

[0024] When scale accumulates inside the inner tank 102, open the electric control valve 801 on top of the descaling tank 6 to allow tap water to enter the descaling tank 6. At the same time, add an appropriate amount of descaling agent through the feed pipe 605. Then start the drive motor 603, which drives the turbine 602 to rotate. The turbine 602 rotates and stirs the liquid in the descaling tank 6, so that the descaling agent and tap water are fully mixed, avoiding sedimentation of the descaling agent and affecting the descaling effect. Close the control valve 402 at the bottom of the water supply valve and open the external control valve 402 of the branch pipe 401. The branch pipe 401 opens the bottom end of the descaling liquid flow drain pipe 4 into the inner tank 102. Start the steam generator body 1 to heat the tank, so that the agent reacts fully with the scale and removes the scale inside the inner tank 102. The waste liquid is discharged from the inner tank 102 through the drain pipe 103. This descaling method is simple to operate, suitable for thin and medium-thickness scale, and causes less damage to the equipment.

[0025] In this embodiment, a support frame 9 is provided on one side of the steam generator body 1. The bottom of several columns of the support frame 9 are attached to the top of the steam generator body 1. The water supply tank 5 and the descaling tank 6 are both located on the top of the support frame 9. An automatic control device 901 is fixedly connected to the outside of one side of the column of the support frame 9 by bolts. The automatic control device 901 is located at the bottom of the descaling tank 6.

[0026] In use, the support frame 9 supports the water supply tank 5 and the descaling tank 6. The top of the support frame 9 is hollow, which facilitates the connection of the drain pipe 4, the branch pipe 401 and the water supply tank 5 and the descaling tank 6. The automatic control device 901 has control operation functions for the water supply tank 5, the descaling tank 6, the electric control valve 801 and the control valve 402, which is convenient for the staff to operate.

[0027] In this embodiment, a level gauge 601 is fixedly installed on one side of the descaling tank 6, a branch pipe 401 is fixedly connected to the bottom of the descaling tank 6, a drain pipe 4 is provided on one side of the branch pipe 401, the top end of the drain pipe 4 is fixedly connected to the bottom of the water supply tank 5, the tail end of the branch pipe 401 is fixedly connected to the outside of the bottom end of the drain pipe 4, and control valves 402 are fixedly connected to the outside of both the branch pipe 401 and the drain pipe 4.

[0028] In use, several control valves 402 and electric control valves 801 can control the water supply and drainage of the water tank 5 and the descaling tank respectively, avoiding the need for workers to lift water to replenish the descaling tank 6. The level gauge 601 allows staff to monitor the water level inside the descaling tank 6 in real time.

[0029] In this embodiment, the tail end of the branch pipe 401 is connected to the bottom end of the control valve 402 of the drain pipe 4. The bottom of the branch pipe 401 is provided with a steam generator body 1. The top of the steam generator body 1 is fixedly connected to the inlet pipe 104. The bottom end of the drain pipe 4 is located inside the inlet pipe 104. The steam generator body 1 includes an electromagnetic heater 101 and an inner tank 102. The electromagnetic heater 101 is fixedly connected inside the steam generator body 1.

[0030] When in use, when a thick or stubborn scale appears on the inner wall of the inner tank 102, the main body 1 of the steam generator stops operating and the control valve 402 is activated, so that the tap water in the water tank 5 enters the inner tank 102 through the water inlet pipe 104. At the same time, the vibration frequency and duration of the ultrasonic transducer 302 are adjusted through the control panel of the main body 1 of the steam generator, so that the ultrasonic waves penetrate the vibrating plate 301 and the high temperature insulation layer 2 and enter the interior of the inner tank 102, causing the scale layer on the inner wall of the inner tank 102 to gradually break down.

[0031] In this embodiment, the electromagnetic heater 101 is provided with a high-temperature heat insulation layer 2 at the top. The high-temperature heat insulation layer 2 is fixedly connected to the outside of the top of the inner liner 102. The top of the high-temperature heat insulation layer 2 is fixedly connected to an outer shell 3. The outer shell 3 includes a vibrating plate 301 and an ultrasonic transducer 302. The ultrasonic transducer 302 is fixedly connected to the top of the inner shell 3, and the bottom of the ultrasonic transducer 302 is fixedly connected to the top of the vibrating plate 301.

[0032] During use, the descaling agent inside the descaling tank 6 can be added to the inner wall. The descaling agent, together with the ultrasonic waves, can remove thick or stubborn scale from the inner wall of the inner tank 102. The ultrasonic transducer 302 can handle areas that are difficult for machinery to reach, such as narrow gaps or curved pipes, while avoiding scratching and damaging the metal surface. The high-temperature insulation layer 2 is made of high-temperature resistant material and has a heat insulation function to prevent the high temperature on the inner tank 102 from being transferred to the outer shell 3 and affecting the operation of the ultrasonic transducer 302.

[0033] In this embodiment, the vibrating plate 301 is fixedly connected to the bottom of the outer shell 3. The bottom of the vibrating plate 301 is fixedly connected to the high-temperature insulation layer 2. The top pipe of the inner liner 102 passes through the high-temperature insulation layer 2 and the outer shell 3 and is connected to the bottom of the water inlet pipe 104. The inner liner 102 is located inside the electromagnetic heater 101. The outer wall side of the steam generator body 1 is integrally connected to the drain pipe 103. The top of the drain pipe 103 passes through the electromagnetic heater 101 and is connected to the bottom of the inner liner 102.

[0034] During use, the electromagnetic heater 101 heats the inner tank 102, and the descaling agent reacts fully with the scale, causing the scale to dissolve and detach from the inner wall of the inner tank 102. The scale and descaling agent mix to form waste liquid. The operator opens the drain pipe 103 through the control panel of the steam generator body 1 to drain the waste liquid inside the inner tank 102. After draining the waste liquid, tap water from the water tank 5 needs to be added to the inner tank 102 to repeatedly flush the inner tank 102 to avoid the agent residue affecting the use of the steam generator body 1.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When scale accumulates inside the inner tank 102, the electric control valve 801 at the top of the descaling tank 6 is opened to allow tap water to enter the descaling tank 6. At the same time, an appropriate amount of descaling agent is added through the feed pipe 605. Then, the drive motor 603 is started, and the drive motor 603 drives the turbine 602 to rotate. The turbine 602 rotates to stir the liquid in the descaling tank 6, so that the descaling agent and tap water are fully mixed, avoiding the sedimentation of the descaling agent from affecting the descaling effect. The control valve 402 at the bottom of the water supply valve is closed, and the external control valve 402 of the branch pipe 401 is opened. The branch pipe 401 opens the bottom end of the descaling liquid flow drain pipe 4 and enters the inner tank 102. The main body of the steam generator 1 is started to heat the tank, so that the agent reacts fully with the scale and removes the scale inside the inner tank 102. The waste liquid is discharged from the inner tank 102 through the drain pipe 103. After the waste liquid is emptied, tap water from the water tank 5 needs to be added to the inner tank. 102. Repeatedly rinse the inner tank 102 to avoid chemical residue. This descaling method is simple to operate, suitable for thin to medium-thickness scale, and causes less damage to the equipment. When thick or stubborn scale appears on the inner wall of the inner tank 102, after the steam generator body 1 stops operating, start the control valve 402 to allow tap water from the water tank 5 to enter the inner tank 102 through the water inlet pipe 104. At the same time, adjust the vibration frequency and duration of the ultrasonic transducer 302 through the control panel of the steam generator body 1 to allow the ultrasonic waves to penetrate the vibrating plate 301 and the high-temperature insulation layer 2 into the inner tank 102, causing the scale layer on the inner wall of the inner tank 102 to gradually break down. At the same time, the descaling agent in the descaling tank 6 can be added to the inner wall, so that the descaling agent, together with the ultrasonic waves, can remove the thick or stubborn scale on the inner wall of the inner tank 102. The ultrasonic transducer 302 can handle narrow gaps or curved pipes and other areas that are difficult for machinery to reach, while avoiding scratching and damaging the metal surface.
